Specification of Letters Patent.

Pa tented Sept. 28,1915.

Application filed June 12. 1914. Serial No. 844.743.

To all whom. it may concern} Be it known that I. Tnrrnr. L. Bosn wicu, a citizen of the l nited States, resid ing at Burlington, in thecounty of Chit tendcn and State ofl'ermont. have invented a new and useful ConstructionBlock, of which the following is a specification.

T his invention relates to improvements in construction blocks designed either for use in the construction of toy objects or, on a larger scale. for use in the construction of display racks, drying racks. and similar articles.

One of the objects of the-invention is to provide a construction block consisting of a unit having six approaches or. in other words. apertured faces, any one of the apertures being adapted to receive a dowel which can be of any preferred length. the dowels being adapted to frictionally engage the walls of the apertures and. after a predetermined combination of units has been set up, the parts will remain in the positions in which they have been arranged.

With the foregoing and other objects in view \vhich'will appear-as the description proceeds, the invention resides in the combination and arrangement of parts and in the of construction hereinafter dothat changes in the precise embodimcntof the invention herein disclosed, can be made within the scope of what is claimed. without departing from the spirit of the invention.

In theaccompanying drawings the preferred forms of the invention have been shown.

In said drawings :-Figure 1 is a perspective view of one of the units or coupling blocks forming a part of the present invention. Figs. 2 and 3 are perspective views of dowels or connecting blocks to be used in connection with approach blocks. Fig. 4 is an enlarged section through a. coupling block and showing dowels or connecting blocks extending. therefrom. Fig. 5 is a perspective view of a form of display rack or reel which may be constructed by the use of units such as constitute the present invention. Fig. 3 is a persp ctive view of an other l'orm of display rack which can be constructed by the use of the units consti tilting the present invention.

Referring to the. figures by characters of reference 1 designates a coupling l l()('l\' which, in the present instance, is a cube formed of any desired material. there being a circular opening 2 in the center of each face of the cube. these openings extending entirely through the block. Dowels or connecting blocks 3 of different lengths are designed to be used in connection with the coupling blocks. these dowels likewise being preferably formed of wood and being adapted to lit snugly. within the openings By providing a coupling block having an opening in the center of each of its faces, a large number of combinations can be de vised. For example. and as shown in Fig. a base can be made up of four coupling blocks connected by dowels. each end of the .E have coupling blocks l which. in turn. are

connected by dowels i. Thus it will be seen that a reel structure or a display rack is provided and. by having the dowel C fitted loosely in the coupling blocks B. a pulley 4 can be fitted onto one end of the dowel C and the reel thus rotated in any suitable manner, thus aii'ording an amusing toy when the device is built on a small scale.

Another structure which can be built up of blocks such as constituting the present invention. has been illustrated in l 6; this structure consisting of a base ll made up of four coupling blocks and connecting dowels. and standards I made up of dowels on which coupling blocks J are mounted. these conplingblocks being connected by dowels K. Additional coupling blocks I) can be mounted on the middle portions of certain of the dowels K and can be connected by a cross dowel M supporting a long dowel N constituting a central standard on which several approach blocks 0 can be mounted. Pegs 1 formed of short dowels are extended upwardly from the coupling blocks J and L and each of th coupling' blocks U can be provided witb dowels (3 extending from the side faces thereof. Home of the dowels can be short so as to form pegs, as shown at B, while ithcr dowels can be long so as to support approach blocks S from which the short dowels are extended to constitute horizontal and vertical pegs T. It will be obvious of course that various other combinaiions of. approach blocks and dowels can be utilized for the purpose of' getting structures different from those illustrated. by uslng blocks of small sizes, they can be employed in the constructlon of toyurticles. Whereas by utilizing large sized blocks, articles of full size, such as display furniture and the like can be constructed.

What is claimed is The combination with a plurality of cubes, each having an aperture in each face thereof and extending entirely therethrough, of dowels of uniform diameter inscrtihle desired distances into any of said apertures and adapted to cdns'bitute mnneccions between the cubes.

'In testimony that I claim the foregoing us my own, I have hereto allixcd my signalture in the presence of We Witnesses.
